PT XYZY merupakan salah satu perusahaan yang bergerak pada bidang industri alat elektronik. Proses produksi kulkas di PT XYZ, khususnya pada lini vacuum forming, salah satu lini produksi yang defect produk tertinggi diantara lini produksi lainnya yaitu mencapai 7,2%. Selama periode April-November 2023 BU Refrigerator mencatat defect produk pada proses produksi inner liner, yaitu inner liner sobek, kotor, berurat, tipis, dan berbintik. Defect tertinggi terjadi pada bulan Juni dengan 1046 unit sebesar Rp29.091.331, yang terus meningkat hingga Agustus menjadi 1442 unit sebesar Rp41.302.947. Penelitian ini bertujuan untuk mengidentifikasi penyebab cacat pada produksi inner liner kulkas serta memberikan rekomendasi perbaikan menggunakan metode Quality Control Circle (QCC). Jenis cact yang dianalisis adalah inner liner berbintik, yaitu cacat tertinggi dengan persentase 28% dari total cacat produksi. Penelitian ini menggunakan metode PDCA (Plan-Do-Check-Action) untuk menganalisa penyebab cacat dengan alat bantu seperti diagram pareto dan diagram fishbone. Hasil analisa menunjukkan bahwa faktor metode, kurangnya pelatihan bagi operator baru, menjadi penyebab dominan cacat inner liner berbintik. Rekomendasi yaitu peningkatan pelatihan intensif bagi operator baru, perawatan mesin yang lebih baik, dan peningkatan kualitas material untuk menurunkan tingkat defect serta meningkatkan kualitas produksi agar menambah profit perusahaan.

PT XYZY is one of the companies engaged in the electronic appliance industry. The refrigerator production process at PT XYZY, specifically on the vacuum forming line, is one of the production lines with the highest product defects among other production lines, reaching 7.2%. During the period from April to November 2023, the BU Refrigerator recorded product defects in the production process of the inner liner, including torn, dirty, streaked, thin, and speckled inner liners. The highest defect occurred in June with 1,046 units amounting to Rp29,091,331, which continued to increase until August to 1,442 units amounting to Rp41,302,947. This study aims to identify the causes of defects in the production of inner liners and provide improvement recommendations using the Quality Control Circle method. (QCC). The type of defect analyzed is the speckled inner liner, which is the highest defect with a percentage of 28% of the total production defects. This research uses the PDCA (Plan-Do-Check-Action) method to analyze the causes of defects with tools such as the Pareto diagram and the fishbone diagram. The analysis results show that the method factor, specifically the lack of training for new operators, is the dominant cause of the spotted inner liner defects. The recommendations are to improve intensive training for a new opeators, enhance machine maintenance, and upgrade material quality to reduce defect rates and improve production quality, thereby increasing the company's profit. . Keywords: Inner liner, Quality Control Circle (QCC), Defect, PDCA, Fishbone diagram, Pareto Diagram.
